@param pattern input which may contain '%' or '_' wildcard characters, or

@return replace %/_ with regex search characters, also handle escaped

The datanucleus module expects the wildchar as '*'. The columns search on the
other hand is done locally inside the hive code and that requires the regex wildchar
format '.*' This is driven by the datanucleusFormat flag. | [
